Hi,

I didn't track the details of the argument, but I would hope that
there is a way to coerce your sh program to be compliant, or else
rig it so that $(command -p -v sh) yields one that is.  As rare
as ``var=foo myfunc ; echo ${var+SET BY MISTAKE}'' constructs might
be, it is nice to now that forcing posix mode  will put "portable"
shell scripts into the right environment.  Dumb as it may be.

Thanks!  - Bruce (a tries-to-be portable shell script writer)
